A receptacle (500) is provided for coupling an adaptor (10) having a vial (54) including a beneficial agent to an IV administration set (526). In an embodiment, the receptacle (500) includes an injection site (512) for receiving a cannula (26) from the adaptor (10). A resilient divider (516) separates the receptacle (500) into two sections defined by an upper fitment (508) and a lower fitment (510). A container (520) holding a solution is in fluid communication with the receptacle (500) via an inlet (502). A through bore (518) allows the solution from the container (520) to pass through the resilient divider (516) when the adaptor (10) is removed from the receptacle (500).

In-line drug delivery device for use with a standard IV administration

A drug delivery device (250) is provided for coupling a container (260) including a beneficial agent (262) to the device (250). The device (250) includes a substantially hollow member for housing a solution (256) wherein the hollow member includes an upper section (254) having flexible walls and a lower section (252) having substantially rigid walls. A spike (258) extends from the lower section (252) to provide fluid communication between an interior of the device (250) and the container (260). To this end, the beneficial agent (262) mixes with the solution (256) forming a mixture for administration to a patient. A cannula (266) and a plunger (264) are further provided for administration of the mixture (270) to the patient.

A drug delivery device is provided for coupling a first container including a beneficial agent to a second member. In an embodiment, the device includes a substantially hollow member having a cannula mounted within a wall that divides the substantially hollow member into a first and second section. The first section includes means for receiving at least a portion of a first container. The substantially hollow member includes a wall that defines an exterior of the first section that is substantially flexible. A number of different cannula and flow path structures within the hollow member are possible pursuant to the present invention.

Adaptor for drug delivery

The present invention provides an improved cannula that can be used to reconstitute powdered drugs in a drug delivery system. Furthermore, the present invention provides a cannula and drug delivery system incorporating same. To this end, the present invention provides a cannula structure for use in a reconstitution device for reconstituting a powdered drug comprising a cannula having a first end and a second end, and defining a channel in an interior thereof between the first and second ends. The first end is closed and includes a member for piercing a septum. The cannula includes at least two slots providing fluid communication between the channel and an exterior of the cannula. The slots are located in juxtaposition to the first end and have a width, as measured along a length of the cannula, that is less than a length, as measured around the cannula. The slots also have a minimum projected area equal to or greater than the cross-sectional area of the channel.
